Windscreen material

[Jim Alex]

I am replacing the transparencies on my Jodel 120. 3mm screens are fitted at the moment, so I plan to use 3mm acrylic (Perspex) to replace them. Any comments?

Hi Alex,

Can I suggest that you try to source some UV stablised PETG. It is amazing stuff and most importantly fuel resistant.

Buy a big sheet, otherwise fairly straightforward.
UV stablised PETG new one on me is it easy to work?.

[ThePipster]

Yes, PETG is very easy to cut and trim and it will bend to a radius in excess of 90 degrees without breaking up. Better still it also doesn't require special drill bits to prevent cracking when making holes, I can't praise it enough!

I wish I'd asked the same question before I replaced my D117 panels last year! I used 3mm polycarbonate for the screen and 2mm acrylic for the doors. I have to be very careful when refueling my front tank. Phil, how does the strength and crack resistance of PETG compare with polycarb?

Hi Mike,

It is as strong as Lexan but more flexible.The only downside is that like Lexan it scratches more easily than acryllic (perspex). The actually compund is the same as plastic coke bottles!

Thanks for the info, but I am going to use cast Perspex which I can source locally. Polycarbonate is a no-no as it is almost unbreakable.

Unless exposed to petrol which makes it very breakable!
